Title: Improvements in power-directional relays
IPC: H02H1/00
Filed: 1933-06-19
Abstract: 405,531. Protective cut-out systems. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. June 19, 1933, No. 17463. Convention date, June 20, 1932. [Class 38 (v).] A directional wattmeter relay is arranged to be responsive to earth faults on one phase, faults between two phases, and three-phase faults, by making it responsive to the residual and inverse components of the power (or to the latter alone, in which case two separate relays are used), and by automatically transforming it into a relay sensitive to the direct component or to the total polyphase power when a threephase fault occurs. The relay 1 has elements 2, 3, 4, the current windings of which are energized from current transformers 6 in the respective phases A, B, C of the line, and by the residual current io. The windings of element 2 produce a flux proportional to (iA-iB), those of 3 a flux proportional to (ic-io /3), and the turns of the windings of elements 2, 3 are chosen so that their respective fluxes are proportional to (iA-iB): #3 (ic-io /3), so that with a balanced load the fluxes are equal and in quadrature. The voltage windings of elements 2, 3 are energized through contacts of a relay 19 from a mesh comprising T-connected transformers 13, 14, condensers 15, 16, and resistances 17, 18, the transformers being energized from a potential transformer 9 in the line. The voltage winding of element 4 is connected between the neutral of the secondary of that transformer and an artificial neutral derived from impedances 21, and is arranged so that the torque of element 4 is responsive to the residual component, which is additive to that of the inverse components energizing elements 2, 3. With a three-phase fault, these components may be too small to operate the relay, hence three overload relays 24, with contacts in series, are arranged to energize relay 19 to alter the connections of the voltage windings, so that the latter are connected directly to the transformers 13, 14 and thereby the relays are made responsive to the total three-phase power. Undervoltage or minimum-impedance relays may replace the overload relays.

Title: Amplifier circuit for high frequency transmission, comprising a carrier stage and an additional stage
IPC: H03F1/06
Filed: 1952-07-11
Abstract: 719,502. Modulating systems. STANDARD TELEPHONES & CABLES, Ltd. July 11, 1952 [July 12, 1951], No. 17568/52. Class 40 (5)  In a high efficiency amplitude modulated transmitter having two branches, the output stage, of the main branch being coupled over an inverting network to the load while the output stage of the auxi'iary branch is coupled directly to the load, each branch is fed from a carrier source and a separate output of a modulating stage. The modulation stage and output stage of a branch comprise a grounded cathode tetrode and a grounded grid triode respectively connected to a common bias source. Carrier, from valve R01 is fed over transformer L1, L2, L3 to driver valves R06, R08 supplying power to grounded-grid valves R07, R09. The networks L6, L7 and L10, L11 cause the drive on the carrier amplifier R07 to be in phase quadrature with that in auxiliary amplifier R09, the phase being corrected over tuned transformer L8, L9 feeding the load R9. The modulating signal is applied over amplifiers R02, R03 and cathode followers R04, R05 to the drive valves R06, R08, the bias derived from potentiometer R19 determining when the auxiliary stage will become effective. In order to linearize the modu!ation, the demodu'ated output from rectifiers G1 is fed to the input of the modulator while the output from rectifiers G2 is fed back to the grid circuit of cathode follower R05. Grid current feedback is operative over the common resistor R6 in the cathode lead of drive valve R06 and the grid lead of valve R07.

Abstract: 1,178,815. Articles from inflatable parts. S. P. VACI. 15 July, 1968 [16 April, 1968], No. 17815/68. Heading A6S.

Title: Improvements in transmission volume control systems for electric signalling
IPC: H04B3/06
Filed: 1929-06-10
Abstract: 334,869. Electrical Research Products, Inc., (Assignees of Mitchell, D., and Silent, H. C.). Dec. 17, 1928, [Convention date]. Automatic gain control. - In an automatic volume control system for radio telephony or for long submarine telephone cables, means are provided to prevent hunting when the energy level is constant, and in a two-way system for holding the transmitting channel automatic volume control means constant while the receiving channel is operative. Fig. 1 shows a one-way channel L2' L, and amplifier 3 and a volume control potentiometer PI operated by control apparatus 4. The volume control apparatus may comprise motor or relay operated devices or thermionic valve arrangements controlling grid biases or impedances. An amplifier-detector 2 bridged across the input is arranged to operate a weak volume relay A while the output amplifierdetector 1 operates a high volume relay E, and a correct volume relay B, which control relays C, D, associated with the control apparatus 4. Relay C is slow to release and relay,D slow to operate so that increase of the signal volume is only effected if relay E is maintained energized. At the conclusion of conversation the relays return to normal without affecting the potentiometer setting, i.e., the system is " full neutral." Fig. 3 shows a system normally set for maximum gain by omission of the minimum input relay A so that in the absence of signals the potentiometer P1 returns to maximum setting. Relay 20 is operated from the receiving channel and by energizing relay G prevents the operation of the control apparatus 4 while the receiving channel is operative. The control apparatus 4 in addition preferably is extended to control the gain in the receiving channel in the opposite sense to the control effected. in the transmitting channel to prevent singing or echo. In a modification (Fig. 2, not shown), provision is made in the absence of signals to return the potentiometer to a setting to give any required normal gain. Fig. 5 shows a semi-neutral system which returns to an increased gain setting after the loudest speaker, but is neutral after all other speakers. Contacts S1, S0 normally close the increase and decrease gain circuits respectively when the relays are normal and thus return the control apparatus 4 to a normal setting while contact S, operates relay F to decrease the sensitivity of the input amplifier-detector 2. Return to minimum by contact So during pauses is prevented by slow release relay H.

Title: Method and means for effecting the separation of subdivided materials
IPC: B03B5/62
Filed: 1927-07-07
Abstract: 286,951. Marks, E. C. R., (Susquehanna Collieries Corporation). July 7, 1927. Density separators. - Subdivided material is subjected, to the action of a vortex in liquid and is arranged in horizontal strata of different specific gravities, and the lighter substance is removed upwardly. The apparatus is described with reference to the separation of coal and slate. A cylindrical receptacle A with a conical bottom B has a tangential rectangular inlet H and an axial discharge pipe D with an adjustable end E. A curved discharge pipe I runs from the conical bottom B to the conical bottom K of a cylinder J which has a tangential inlet P and an axial discharge pipe M with an adjustable end N. The mixture of coal and slate is supplied through the feed pipe G, and water under pressure is introduced through the inlets H, P. The water whirls round in each cylinder A, J and rises through the discharge pipes D, M. The material of the mixture supplied builds up a bed occupying the tube I and the lower part of each cylinder; the surface in each cylinder assumes a conical form owing to the motion of the water. The coal, being the lighter material and subject to less frictional resistance than the slate, remains on the top of the bed in the cylinder A. By proper adjustment of the flow of water and of the discharge pipe ends E, N, pieces of coal are swept up the discharge pipe D and pieces of slate up the discharge pipe M. In the modified form of apparatus shown in Fig. 3, one cylinder A alone is employed and has concentric discharge pipes D', M<1> for coal and slate respectively, while the water to carry the slate away is introduced through the pipe P<1>. A circulatory system may be adopted for the water, which can be pumped through the apparatus and restored to the supply tank. Where slimes are included in the mixture, they are separated by a first passage through the apparatus, and the coal and slate are separated by a second passage.
